We do this route when the west wind (poniente) is blowing, heading towards Agua Amarga and finishing at Cala del Puente, named after a striking natural rock arch. Along the way the volcanic textures of the rocks are remarkable. We pass Cerro Negro and Cala Hernández, then Cala de San Pedro, the only beach here with a freshwater spring, watched over by San Pedro castle; in summer we prefer not to stop there, as it gets very crowded. Opposite lie San Pedro islet, Punta de la Javana and the coves of Montoya and La Chumba, all unreachable by land, with beautifully shaped rocks. At Cala del Puente we stop for a swim and some excellent snorkelling before heading back to Las Negras.
